The government finished up the first week of testimony in the James "Whitey" Bulger trial by calling two bookmakers to the stand. James Katz and Richard O'Brien told jurors what it's like to work in the illegal gambling industry with the likes of Bulger and his associates. Suffice it to say it wasn't pleasant.

Although Katz and O'Brien served time behind bars for their crimes, they eventually received reduced sentences and other favorable arrangements in exchange for their cooperation. The two elderly men will be the first of many witnesses to testify about the ins and outs of the deals they received from the government.

With Week 1 of U.S. v. Bulger now behind us, here are the five details most likely to be remembered when the case comes to an end many months from now:

1. The 19 photographs. Toward the end of Assistant U.S. Attorney Brian T. Kelly's opening statement on Wednesday, the veteran prosecutor listed, by first and lastname, the identities of Bulger's 19 alleged murder victims. As Kelly slowly read the names, he placed their photographs on a screen and paused as jurors looked at each image. The dramatic courtroom moment is bound to be something this jury won't soon forget.

2. Sweetheart deals. Over the past few months, U.S. District Court Judge Denise J. Casper has thwarted the efforts of defense attorneys J.W. Carney Jr. and Hank B. Brennan to argue that Bulger had immunity to commit the crimes for which he is under indictment. The rulings, which have been properly preserved in the event of a conviction, left many wondering exactly what direction the defense would go at trial. The answer came during Carney's powerfully delivered opening: that the three key government witnesses all made "too good to be true" deals with the feds and can't be believed because they'll say whatever they need to in order to keep the prosecution happy.

3. "Seriously?" Carney and AUSA Fred Wyshak are two experienced attorneys. On the eve of the trial of the century, a heated clash in front of Casper was one for the ages. The defense was in the process of accusing the government of a cover-up when Wyshak accused Carney and Brennan of going on an inappropriate fishing expedition. "It's unlawyerly and unprofessional," Wyshak said. "And I hope that this conduct doesn't continue throughout the course of this trial." A clearly perturbed Carney loudly interrupted, saying "It is going to continue." It was perhaps not Casper's finest judicial moment when she tried to stop the bickering by asking, "Seriously?"

4. Guns and books. There's no better way to let a jury see what organized crime looks like than by marching out a bunch of machine guns and revolvers. State Police Col. Tom Foley had the jury's attention when he lifted up and identified each weapon presented to him by Wyshak. Foley also became the first of several witnesses to take the stand who have penned tell-all books on the Bulger saga. Foley, who was skillfully cross-examined by Brennan, found out that the written word can have a way of coming back to bite you.

5. The sleeping juror. Perhaps too much was made of the fact that one of the younger members of the jury pool dozed off during the trial. Anyone who has spent time inside a courthouse knows that it's not unheard of for a juror to be caught napping. But it was curious that the juror fell asleep during opening statements of the most anticipated trial in state history. To his credit, the juror has picked up the pace in recent days and is a regular note-taker who appears to be closely following the action. In the meantime, the guy has become somewhat of an Internet sensation. An @SleepyJuror twitter account has already accumulated 135 followers.
